Overview
Spelljammers are flying ships to travel the world, and the space between worlds. They, like Elven Cities, work by sacrificing spell slots. This magical power is turned from potential into propulsion. Spelljammers are rated by their size, and the quality of their Spelljamming Helm
Spelljammer Type Categories:
Corvette: lightly armed, fast sailing vessel
Cutter: small naval vessel, fore-and-aft rigged, single mast with two headsails
Frigate: a ship-rigged warship with a single gundeck
Ship of the line: the largest warship
Spelljammer Speed:
When you spend a spell slot to power your spelljammer, add 1 to the energy in the spelljammer for the slot itself, and then add the level of the spell slot expended. You can spend the spelljammer’s energy 1-for-1 on either speed or duration of travel.
